Notes:

Positive Carbon Dioxide Identification is achieved when the Assay results demonstrate meeting the specification.
The limit of detection (LOD) for each test method is the threshold value for results to be reported with certainty in the accuracy of results. A test result outside the detection limit for the test method will be reported as ND.
ND = None Detected
ppm = parts per million by volume, ppb = parts per billion by volume, 1 ppm = 1,000 ppb
